I've lost 35 pounds over a few months before I was diagnosed. Once started on medication I gained it all back in less than a year. Feel very lucky.

I did. Lost 40 pounds in 8 months and was functioning on 20 percent of dopamine until I was diagnosed with pd.

Thank you for your answer.

Many have lost some weight due to 'loss of appetite'. I lost about 15lbs in 6-7 weeks.

Quite a few do.
